Chemical Structure
Description
The occurrence of 3,3'-Disulfo-[1,1'-biphenyl]-4,4'-dicarboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,3'-Disulfo-[1,1'-biphenyl]-4,4'-dicarboxylic acid (CAS 470466-07-0), a certified reference material (molecular formula C14H10O10S2, MW 402.35 g/mol) for analytical method development and quality control.
Structurally, 3,3'-Disulfo-[1,1'-biphenyl]-4,4'-dicarboxylic acid (C14H10O10S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 402.35 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3,3'-Disulfo-[1,1'-biphenyl]-4,4'-dicarboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
